Borescope View is my android app that can show the video output of a USB borescope on a smartphone. Images can be saved by pressing a button in the app or the snapshot button on the borescope. This is not a general use application, it works with my boroscope and can work with others that use the same network protocol. For a description of the protocol, see https://github.com/framenic/freed-borescope
I wrote this application since I don't trust the one provided by the manufacturer, called USB-VIEW (https://play.google.com/store/apps/details?id=com.molink.john.drview). Also, I was worried it could be abandoned in the future, rendering the borescope useless.
An apk of Borescope View can be downloaded at https://github.com/framenic/freed-borescope-view/releases/download/v1.0.0/borescope-view.apk The project has been built and tested under Android Studio 2024.3.1
